Jena is situated in a hilly landscape in eastern Thuringia at the [[Saale]] river, between the [[Harz]] mountains {{convert|85|km|0|abbr=on}} in the north, the [[Thuringian Forest]]/[[Thuringian Highland]] {{convert|50|km|0|abbr=on}} in the southwest and the [[Ore Mountains]], {{convert|75|km|0|abbr=on}} in the southeast. The municipal terrain is hilly with rugged slopes at the valley's edges. The city centre is situated at 160 m of elevation, whereas the mountains on both sides of Saale valley rise up to 400 m. On the eastern side those are (from north to south): the ''Gleisberg'' near Kunitz, the ''Jenzig'' near Wogau, the ''Hausberg'' near Wenigenjena, the ''Kernberge'' near Wöllnitz, the ''[[Johannisberg (Jena-Lobeda)|Johannisberg]]'' near Lobeda and the ''Einsiedlerberg'' near Drackendorf. On the western side, there are the ''Jägersberg'' near [[Zwätzen]], the ''Windknollen'' north of the city centre, the ''Tatzend'' west of the city centre, the ''Lichtenhainer Höhe'' near Lichtenhain, the ''Holzberg'' near Winzerla, the ''Jagdberg'' near Göschwitz and the Spitzenberg near Maua. The mountains belong to the geological formation of Ilm Saale Plate ([[Muschelkalk]]) and are relatively flat on their peaks but steep to the valleys in between. Due to its jagged surface, the municipal territory isn't very suitable for agriculture all the more since the most flat areas along the valley were built on during the 20th century. At the mountains is some forest of different leaf trees and pines.
